Metal hydrides store 1 to 5% hydrogen by weight and require a long time to recharge [55]. Chemically bound hydrogen can store 5 to 15% hydrogen by weight but requires additional energy and complexity to separate the hydrogen [107]. Cryo-compressed hydrogen is pressurized LH 2 stored in a high-pressure cryogenic hydrogen tank (usually 100s of bars).

2.10: Storage of Hydrogen for Use as a Fuel

Hydrogen has a high energy content per weight (more than three times as much as gasoline), but the energy density per volume is rather low at standard temperature and pressure. Volumetric energy density can be increased by storing the gaseous hydrogen under increased pressure or storing it at extremely low temperatures as a liquid.
